CAUTION

After inserting the tab, make sure
the tab and buckle are locked and
that the seat belt extender is not
twisted.

Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.

If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed. It cannot
protect an adult occupant or your
child from injury.
ÐFront seat belt pretensioners
SY13021a
The driver and front passenger 's seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belts are quickly drawn back in by the
retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are acti-
vated even with no passenger in the front
seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.
SU13118
This indicator comes on when the igni-
tion key is turned to the ªONº position.
It goes off after about 6 seconds. This
means the front seat belt pretensioners
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, door side air-
bag sensors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see ªService reminder indicators
and warning buzzersº on page 80 in Sec-
tion 1±5.)

The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.1. Front airbag sensors
2. SRS warning light
3. Airbag sensor assembly
4. Front seat belt pretensioner assemblies
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor. When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smoke±like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries.
NOTICE
Do not perform any of the following
changes without consulting yourToyota dealer. Such changes caninterfere with proper operation of the
front seat belt pretensioners in somecases.
Installation of electronic devices
such as a mobile two±way radio,cassette tape player or compactdisc player
Repairs on or near the front seatbelt retractor assemblies
Modification of the suspension sys-tem
Modification of the front end struc-ture
Attachment of a grille guard (bullbar, kangaroo bar, etc.), snowplow,winches or any other equipment tothe front end
Repairs made on or near the front

CAUTION
A driver or front passenger too close
to the steering wheel or dashboard
during airbag deployment can be
killed or seriously injured. Toyota
strongly recommends that:

The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.

The front passenger sit as far back
as possible from the dashboard.

All vehicle occupants be properly
restrained using the available seat
belts.
SU13118
This indicator comes on when the igni-
tion key is turned to the ªONº position.
It goes off after about 6 seconds. This
means the SRS front airbags are oper-
ating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, door side air-
bag sensors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see ªService reminder indicators
and warning buzzersº on page 80 in Sec-
tion 1±5.)
SU13021
The SRS front airbag system is de-
signed to activate in response to a se-
vere frontal impact within the shaded
area between the arrows in the illustra-
tion.
The SRS front airbags will deploy if the
severity of the impact is above the de-
signed threshold level, comparable to an
approximate 25 km/h (15 mph) collision in
the U.S.A. and 30 km/h (18 mph) collision
in Canada when impacting straight into a
fixed barrier that does not move or de-
form.
If the severity of the impact is below the
above threshold level, the SRS front air-
bags may not deploy.

2001MY ECHO (U) L/O0008
402001 ECHO (OM52440U)
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle ªunderridesº, or goes under,
the bed of a truck, etc.).
It is possible that in some collisions at the
lower zone of airbag sensor detection and
activation the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.
SU13114
Collision from the sideVehicle rollover
Collision from the rear
The SRS front airbags are not designed
to inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or
if it is involved in a low±speed frontal
collision.

Hitting a curb,
edge of pavement
or hard material
Falling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS front airbags may deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.

The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration.1. Front airbag sensors
2. SRS warning light
3. Airbag module for driver (airbag and inflator)
4. Airbag module for front passenger (air- bag and inflator)
5. Airbag sensor assembly
The airbag sensor assembly consists of a
safing sensor and airbag sensor. In a severe frontal impact, the sensors
detect deceleration and the system trig-
gers the airbag inflators. Then a chemical
reaction in the inflators quickly fills the
airbags with non±toxic gas to help restrain
the forward motion of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non±toxic gas. This
does not indicate a fire. This gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential skin irritation.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once. A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.

Do not allow a child to stand up,
or to kneel on the front passenger
seat. The front airbag inflates with
considerable speed and force; the
child may be killed or seriously in-
jured.

Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see ªChild
restraintº on page 51 in this sec-
tion.
SY13033

Do not put objects or your pets on
or in front of the dashboard or
steering wheel pad that houses the
front airbag system. They might re-
strict inflation or cause death or
serious injury as they are projected
rearward by the force of deploying
airbags. Likewise, the driver and
front passenger should not hold
things in their arms or on their
knees.

Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover or front pas-
senger airbag cover, front passen-
ger airbag or airbag sensor assem-
bly. Doing any of these may cause
sudden SRS front airbag inflation or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instructions
can result in death or serious injury.

This indicator comes on when the igni-
tion key is turned to the ªONº position.
It goes off after about 6 seconds. This
means the SRS side airbags are operat-
ing properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, door side air-
bag sensors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see ªService reminder indicators
and warning buzzersº on page 80 in Sec-
tion 1±5.)
SU13125
The SRS side airbag system may not
activate if the vehicle is subjected to a
collision from the side at certain
angles, or a collision to the side of the
vehicle body other than the passenger
compartment as shown in the illustra-
tion.
The SRS side airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side.
For the safety of all occupants, always
wear your seat belts properly.
SU13126
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags are not designed
to inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a low±speed side
collision.

The SRS side airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. SRS warning light
2. Side airbag modules (airbag and inflator)
3. Side airbag sensors
4. Airbag sensor assembly
5. Door side airbag sensor (only for 2±door models)
The SRS side airbag system is controlled
by the airbag sensor assembly. The side
airbag sensors consist of a safing sensor
and airbag sensor. In a severe side impact, the side airbag
sensor triggers the side airbag inflators.
Then a chemical reaction in the inflators
quickly fills the air
bags with non±toxic gas
to help restrain the lateral motion of the
occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non±toxic gas. This
does not indicate a fire. This gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential skin irritation.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats may be hot for several min-
utes, but the airbags themselves will not
be hot. The airbags are designed to inflate
only once.
CAUTION

The SRS side airbag system is de-
signed only as a supplement to the
primary protection of the driver
side and front passenger side seat
belt systems. To ensure maximum
protection in an accident, the driver
and all passengers in the vehicle
must wear their seat belts properly.
Wearing a seat belt properly during
an accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For
instructions and precautions con-
cerning the seat belt system, see
ªSeat beltsк on page 30 in this
section.
